Hey guys, I'm pretty much a newbie to model trains.  I've had HO scale trains through out my life, but never collected or anything of the sort.  I would like to make sure and take good care of the engines, and I have an older engine that I'm sure needs lubing, but don't know which lubes to use and such.  Can anyone help me on this?

Hi, I have a HO SP4449 Daylight loco (item no 41-0550-D9) and on the included parts list is extra smoke fluid.  I don't see anywhere else that the train actually smokes.  Is there a way to find out if it does?  Thanks.
